Ok, I think I've read all the thread correctly and I'm not repeating any question.
Well, now that Yennefer appeared in the Witcher games and there's some discussion about the way she looks, let's ask something related.
At some point in the books Geralt finds out with his penetraiting and detail-spotter witcher eyes, how Yennefer may had been in her youth, before she went through magical phisical transformations (something like magical aesthetical surgery), and knowing that many sorceresses are sent to sorcery academys, because of being ugly or deformed and so without the possibility or marrying some lord and having a proper future.
What phisycal deformity or uglyness does Geralt think Yennefer could have had before becoming a sorceress?
